Check engine light came on a few weeks ago, the code says there's something wrong with either the EVAP canister, the purge solenoid, or a vacuum leak. (And yes, I checked the fuel cap.) I did a visual check on the EVAP canister and components, the only thing that looked amiss was a small bubble on the big hose coming out of the canister. Not a hole, but maybe the hose material is thin enough there to cause a leak? Any suggestions? If it's possible that that is the source of the problem, do I need to replace the entire hose?

Thanks!
